Description

The Atlantic silverside is a slender, semi-transparent fish of the family Atherinopsidae reaching about 15 cm. A conspicuous, shiny silver band runs along the side; the back is greenish and the body has two small, separate dorsal fins. The species forms large schools in shallow coastal water, bays, estuaries and salt marshes along the east coast of North America and tolerates brackish water. It eats zooplankton, small crustaceans, worms and insects. Notably, water temperature during development determines the sex of the young. Through its great numbers it is an important prey fish and a much-used model animal in research.
